ELECTRIC CUT-OUT.

SPECIFICATION forming part of Letters Patent No. 354,466, dated December 14, 1886.

Application filed August 14, 1886. Serial No. 210,884. (E0 model.)

To all whom it may concern.-

Be it known that I, CHARLES Escnwnr, of the city, county, and State of New York, have invented certain new and useful Improvements in Electric Out-Outs, of which the following is a specification.

The invention relates to certain new and useful improvements in automatic cutouts used on electric lights for the purpose of cutting out one or a series of lamps, in case the carbon in the lamp has been consumed or any other part of the lamp is out of order.

The invention consists in a glass block provided with grooves for receiving the linewires, sockets connected with the line and lamp wires, cups between the sockets, bridge-pieces having pinsfitting in the sockets, and fuses secured on the bridge-pieces, all as will be fully described and set forth hereinafter, and finally pointed out in the claims.

In the accompanying drawings, Figure 1 is a plan view of my improved automatic cutout, the same being shown open. Fig. 2 is a longitudinal section on the line a 00, Fig. 1. Fig. 3 is a cross-sectional view on the line yv y, Fig. 2. Fig. 4 is a plan view of one of the bridge-pieces.

Similar letters of reference indicate corresponding parts.

The block A is made of glass or any other insulating material, and is provided with a hinged-top, B. Said block Ais provided with two longitudinal grooves, O G, for the positive and negative wires (6 a, which are held by suitable binding-screws. The positive wire a is connected by the wire b witha socket, D, in that portion of the block A between the grooves G C. At the opposite end the negative wire a is connected by the wire b with the socket D. In the middle part of that portion of the block between the grooves two sockets, E and E, are provided, which are connected with the positive and negative wires 0 c of the lamp F. Between. the sockets D E and D E the caps G- are sunk in the surface of that part of the block A between the grooves O O. The bridgepiece II is made of and provided with springpins I, which can be passed into the sockets D E, respectively, which pins are connected with metal pieces J in the bottom {edge through the pins I I to the line-wires a a. 7

Ordinarily the hinged cover 13 is swung on the block A so as to cover the wires a a, and the bridge-pieces are introduced through the slots M in the hinged cover B. In case the carbons burn out or the lamp breaks, or any other accident occurs, the tension in the circuit of the lamp increases to such an extent that the fuses melt, and the lamp is thus cut out automatically. If one lamp is cut out it does not interfere with the other lamps on the same line-wire. Y

In place of connecting the block A with a single lamp, it may be provided in the same manner with a line on which a series of lights are provided. In case any fuse has been destroyed, the bridgepiece can be withdrawn and a new fuse-piece can be inserted in the bridge in a short time.

Having thus described my invention,Iclaim as new and desire to secure by Letters Patent- 1. The combination, with the electric con ducting'wires, ofabloek ofinsulating material,

provided with grooves through'whieh said wires .are passed, sockets in said blocks con nected with the lamp-wires, bridge-pieces having pins for connecting the main and lamp wires, and fusiblewires on said bridgepieces, which fusible wires are in electrical connection with the main and lamp wires, sub stantially as shown and described.

2. The co1nbination,with a block of insulating material having two grooves, of connectingserews in each groove for making connection with the main line-wires, sockets connected with the said screws, sockets connected with the lamp wires, bridge-pieces having pins fitting in the sockets, and fuses on the bridge pieces,which fuses are connected with the pins, substantially as described.

3. The combination, with a block having on thebridge-pieces, andaslottedhinged cover grooves, of sockets connected with the main on the block, substantially as set forth; and lamp Wires, bridge-pieces having pins, In testimony that I claim the foregoing as metal plates connected with the pins, and fusimy invention I have signed my name in pres- 5 ble pieces connected to the plates below the ence of two subscribing witnesses.
